Sznritech is a China-based ball screw linear driver manufacturer supplying precision motion components to CNC machine builders, robotics integrators, and automated assembly line producers worldwide. Every linear driver we build converts rotary motor input into smooth, low-friction linear motion with micron-level positioning repeatability, the accuracy your production equipment depends on.
We pair our high-precision linear actuators with matched step motors, servo motors, brush motors, and BLDC motors, so you get a complete motion system from a single supplier instead of sourcing components separately.
Why buyers choose our ball screw linear driver line:
• Micron-level positioning repeatability for CNC and automation applications
• A recirculating ball bearing design reduces wear and extends service life
• High load capacity rated for continuous industrial duty
• Magnetic switch-equipped nut slots for accurate position feedback and limit sensing
• Custom torque, speed, and stroke specifications built to your drawing
• Competitive factory-direct pricing with reliable post-sale support
• Export-ready packaging and worldwide shipping
Each ball screw linear driver assembly is built from a drive shaft, end cover, transmission chamber, and recirculating-ball nut that rides along the screw thread. As the motor turns the shaft, the ball nut translates that rotation into precise straight-line travel with far less friction and backlash than a plain lead screw.
The nut slot on every ball screw linear actuator includes a magnetic switch slot, giving your control system reliable position feedback and end-of-travel limit sensing without adding external sensors.
Ball screw linear actuator assembly components:
• Drive shaft / ear shaft
• End cover and transmission chamber
• Recirculating ball nut and screw
• Nut slot with magnetic switch for position feedback
• Mounting slider and screw-thread fixing holes for induction switches
• Best-fit applications for our Precision Ball Screw Actuator:
• CNC machine axes requiring repeatable micron-level accuracy
• Robotic arm linear actuation
• Automated assembly and pick-and-place lines
• Vertical lift and positioning stages (pairs well with our step motors, which hold torque at rest to prevent drift)
Not every application needs a ball screw. If your equipment covers longer travel distances at higher speeds and can tolerate slightly less precision, our synchronous gear belt linear driver is the lighter-weight, lubrication-free alternative. Use this comparison to specify the right driver for your project:
driver for your project:
Choosing the right motor for your ball screw linear actuator depends on your application's load, precision, and duty cycle requirements.
• Step motors—hold torque at rest; ideal for vertical ball screw linear driver installations where drift prevention matters
• Servo motors — closed-loop feedback and dynamic speed control for high-precision ball screw linear driver applications
• BLDC / brushless motors — higher efficiency and longer service life than brushed alternatives
• Brush motors — cost-effective option for medium-duty cycle applications
• All motors are available across multiple voltage configurations to match your existing power infrastructure.
What is a ball screw linear driver used for?
A linear driver converts a motor's rotary motion into precise linear motion. It's used in CNC machines, robotic arms, and automated assembly lines that need repeatable, high-accuracy positioning.
What load capacity can yourlinear driver handle?
Load capacity varies by model and screw diameter—share your application specs (load, stroke, speed, mounting), and our engineering team will recommend the right linear driver configuration.
Can you customize a ball screw linear actuator to our specifications?
Yes. We build ball screw linear actuators to custom torque, speed, stroke, and voltage specifications and can pair them with your choice of step, servo, brush, or BLDC motor.
Do you export ball screw linear actuators outside China?
Yes, we ship ball screw linear actuators and complete motor assemblies to production plants worldwide, with export-ready packaging and after-sales support.
